opensc-explorer: add 'echo' command
Add 'echo' command that simply displays its arguments. With the recently committed script interpreter feature and this echo command, nice litte scripts can be written, like e.g. $ cat opengpg-userinfo #!/usr/bin/opensc-explorer cd 0065 echo Name: cat 005B echo Language: cat 5F2D echo Gender: cat 5F35 quit
